I am trying to set up the Gradebook for one of my courses on my Moodle demo site. Under the 'Gradebook setup', when adding a new Grade Category, I am getting only the "Natural" option for aggregation type. The little question mark next to that setting tells me that there are other options such as Mean, median, lowest, highest, mode, etc but I am not able to see them in the dropdown.
Please see screenshot below:
Is there something that needs to be done in order for the other options to appear?
